[Solved] Custom Survivor: Make every third food restore more Hunger

[Goregonzola]

Hey there!

I'm thinking about a perk to my custom survivor: The final goal would be that every third time he eats something, it would restore some extra Hunger to him.

This is quite a big hurdle I set to myself (I have to get better in coding somehow), I need some kind of reference, to pull this out. The only similar concept that comes to my mind is Warly's memory perk with eating. Could/should I use that as a reference? Do you know something else that resembles this idea more?

I don't expect a polished coding from you, I would be absolutely fulfilled with a pointing to the right direction (, though, if there's a coding bit on the tip of your tounge, I wouldn't refuse it either).

Thanks in advance!

Have a great day!

If I understand correctly, you can use the OnEat function and introduce a simple integer value.

Anything that can eat has the "eater" component and that component has an OnEat function you can set. So you wanna make the OnEat function be something like:

 

local function MyCharacterOnEat(inst)

	if inst.food_counter ~= nil then
		inst.food_counter = 0 --this creates and initializes the food_counter variable if there isn't one already
	end
  
  	inst.food_counter = inst.food_counter + 1 --we increase the counter by one cause we just ate (otherwise this function would not have been executed)
  
  	if inst.food_counter == 3 then -- once we hit 3, we need to apply the bonus
    	-- code that gives extra hunger; haven't looked into how this stuff works and you also haven't mentioned whether you want a flat bonus or a percentage-based one
    	inst.food_counter = 0 --we reset the counter afterwards
    end

end

@QuartzBeam Thanks for the help!

Yep, I would like this perk to be a percentage-based one (namely a 150% one). I've checked Wurt's coding about his veggie bonus, it looks like this:

Spoiler

 inst.components.foodaffinity:AddFoodtypeAffinity(FOODTYPE.VEGGIE, 1.33)

I'm not sure if this could be used a bit edited for every foodtype. If I reconstruct it to this, would it ever work for me?

Spoiler

 inst.components.foodaffinity:AddFoodAffinity(1.5)

Also, is this counter strategy resets the hunger-buff to default after the counter goes back to zero? I've never used this approach before.

Finally, a rookie question: This function needs a ListenForEvent as well, right?

Spoiler

inst:ListenForEvent("oneat", MyCharacterOnEat)

EDIT:

I've tried the coding above, but it crashed with this error:

Spoiler

[string "../mods/devourer/scripts/prefabs/devourer.l..."]:43: attempt to perform arithmetic on field 'food_counter' (a nil value)

This is line 43:

Spoiler

inst.food_counter = inst.food_counter + 1

1. idk anything about foodaffinity, but if you use foodaffinity with upper codes, you will have effect on fourth food, because function(that adds foodaffinity) will called after you actually eat and affected by something.

so you'd better use:

local food = data.food
local foodhunger = food.components.edible:GetHunger(inst)/2
inst.components.hunger:DoDelta(foodhunger)

on that code, because it will add extra 50% hunger of original food to your character.

 

2. Counter does resets,

if inst.food_counter == 3 then -- once we hit 3, we need to apply the bonus

When this line is called(=means it is third food you eat),

inst.food_counter = 0 --we reset the counter afterwards

this line will reset food_counter to zero (@QuartzBeam kindly added remarks each line),

and if you follow my lines wrote in upper section, it would work without problems because bonus hunger will 'added' when only food_counter is 3.

But if you really want to use foodaffinity, you would want to make another line that removes foodaffinity on next eat so bonus will not work everytime you eat.

 

3. Instead of listenforevent, you can just add this line.

inst.components.eater.oneatfn = MyCharacterOnEat

@Combustiblemon Many thanks!

I've puzzled together the codings you suggested, but I think I've messed up something with it's structure. The game crashes when my character consumes something.

I attach my lua file and the servel_log:

devourer.lua server_log.txt

[Combustiblemon]

You have to add "inst.food_counter = 0" in your character's common_postinit.

[Goregonzola]

@Combustiblemon I feel sillier and sillier:

I added "inst.food_counter = 0", but it seems like it always sets the counter to zero because the buff do not applies.

Do I have to specify somehow the "inst.food_counter = 0" to only when the game loads?

[Combustiblemon]

adding "inst.food_counter = 0" on local function onload should work then.

[Goregonzola]

@Combustiblemon I've tried the coding with cooked meat and with carrots, but the buffs still do not apply.

I'll do some further testings, but I don't really know what's messy.

 

[Combustiblemon]

local function WelnyelOnEat(inst)

This line, should be:

local function WelnyelOnEat(inst, data)

this one.

 

if inst.food_counter ~= nil then
	inst.food_counter = 0 --this creates and initializes the food_counter variable if there isn't one already
end

Also this one keeps initializing if food_counter exists.

I think that's typo.

if inst.food_counter == nil then
	inst.food_counter = 0 --this creates and initializes the food_counter variable if there isn't one already
end

This will work.

I didn't knew function does initialize counter, you can just delete "inst.food_counter = 0" in onload or common_postinit.

@Combustiblemon It doesn't seem to surrender so easily. 

It crashes with this message: attempt to index local 'food' (a nil value)

In this line: local foodhunger = food.components.edible:GetHunger(inst)/2

[Goregonzola]

EDIT: I've made it work with a helping hand from another platform. This is the final version:

Spoiler

 

local function WelnyelOnEat(inst, data)

    if inst.food_counter == nil then
        inst.food_counter = 0 --this creates and initializes the food_counter variable if there isn't one already
    end
  
      inst.food_counter = inst.food_counter + 1 --we increase the counter by one cause we just ate (otherwise this function would not have been executed)
  
      if inst.food_counter == 2 then -- once we hit 3, we need to apply the bonus
        inst.components.eater:SetAbsorptionModifiers(1, 2, 1)
    end

    if inst.food_counter == 3 then -- once we hit 3, we need to apply the bonus
        inst.components.eater:SetAbsorptionModifiers(1, 1, 1)
        inst.food_counter = 0 --we reset the counter afterwards
    end

end

 

Thanks for your help @Combustiblemon and @QuartzBeam as well!

Have a nice day everyone!
